Split Mounting Type Square Column Assembly

ABSTRACT

The present invention relates to a split mounting type square column assembly for the exhibition equipment, comprising a square column, a embedded type supporting frame, and a connecting lock, wherein the said connecting lock may be removable located within the said embedded type supporting frame, and the said embedded type supporting frame may be removable located within the said square column. One outside surface of the said square column at least has a connecting groove, and has a quantity of positioning mounting holes in the area except for the situation of the said connecting groove. Said embedded type supporting frame consists of a supporting frame body, a spring cotter and a spring keyway, wherein, said spring cotter is located within the said spring keyway, and in the initial state, said spring cotter overhangs from the said spring keyway, said spring keyway is located on the said supporting frame body, therefore the moving pathway of said spring cotter could pass through the positions of said positioning mounting holes when said embedded type supporting frame is pushed in or out.

FIELD OF THE INVENTION

The present invention relates to an assembly of combined type exhibition equipment, particularly to a split mounting type square column assembly.

BACKGROUND OF THE INVENTION

The prior art employs guide rails in square columns and internally assembled connecting pieces. The connecting pieces are fixed by screw fastening. However, since the retaining screws must have countersunk heads, which must pass through existing grooves to implement tightening, the grooves have to be cut partially to enable the screws to pass through; as the result, there is a potential safety hazard, i.e., if the Operation points of forepaws of connectors in other adjacent supports are right in the cut part of the groove, the connection points are not connected actually or false connected. For exhibition supports, the consequence may be connection failure of the supporting structure and may result in personal injury.

SUMMARY OF THE INVENTION

The present invention provides a split mounting type square column assembly that facilitates assembling of the exhibition equipment and improves safety and reliability of the exhibition equipment.

The present invention employs the following technical scheme:

A split mounting type square column assembly for exhibition equipment, comprising a square column 1, a embedded type supporting frame 2 and a connecting lock 3; wherein, said connecting lock 3 is removable located in said embedded type supporting frame 2; said embedded type supporting frame 2 is removable located in said square column 1, at least one outside surface of said square column 1 has a connecting groove 11, and a quantity of positioning mounting holes 12 is arranged on the outside surface of said square column 1 outside of the area of connecting groove 11; said embedded type supporting frame 2 comprises a supporting frame body 21, a spring cotter 22 and a spring keyway 23; said spring cotter 22 is located on said spring keyway 23; in the initial state, said spring cotter 22 overhangs from said spring keyway 23, said spring keyway 23 is located on said supporting frame body 21, therefore the moving pathway of said spring cotter 22 could pass through the positions of said positioning mounting holes 12 when said embedded supporting frame 2 is pushed in or out.

Compared to the prior art, the present invention has the following advantages:

-   (1) In the present invention, the connection between the square     column and the embedded type supporting frame is arranged outside of     the area of connecting groove that is designed to connect other     parts of the exhibition equipment; therefore, the present invention     ensures completeness or integrity of the connecting groove, so that     it is unnecessary to consider the effect of assembling holes in the     connecting groove when said exhibition equipment is assembled, and     reliable connection can be implemented at any position in said     connecting groove; as the result, the present invention can     facilitate assembling of the exhibition equipment and improve safety     and reliability of the exhibition equipment. -   (2) The plates that constitute the square column are removable     connected, and thereby provide more convenience for assembling of     the exhibition equipment. -   (3) The present invention employs a spring pin for connection; the     spring pin can implement accurate fitting between internal     connecting pieces (inserts) and outer surface of the profile, and     thereby ensures required accuracy. Furthermore, it is common     knowledge that it is much easier to work out locating holes on outer     walls than on complex shapes (e.g., walls with uneven wall     thickness, half openings, cantilevers, or bevel surfaces, etc.).     Employ spring pin structure can avoid fixing holes or fabrication     holes on outer finished surfaces; since the pin structure level up     the pin hole after it is assembled to the section of profile, it can     maximize appearance perfection. In addition, since the mounting     point of the structure is above or below the joint, the structure     can avoid adverse effect to the finishing work on left and right     surfaces at the joint as far as possible.
